Last summer we posted a photo from Major Lazer’s visit to No Doubt laboratories, where Diplo and Switch made nice with Gwen Stefani’s crew and, according to @NoDoubt’s tweet that day, worked on a collabo track called “Push And Shove.” That demo has survived every subsequent production, label, and band meeting to the point that it’s official recording is the subject of this little webisode in which No Doubt look incredibly well preserved and discuss the means via which this artist-merger came to pass. (Hint: Jimmy Iovine.) You’ll hear bits of the song, paired with confessionals from Tony and Gwen, in the embed below:

The new No Doubt album is due in September, with its first single out this July.
